SK-2232 client initialisation for java flow db sdk

[skyflow-bharti]

Why:

Java FlowDB currently lacks client initialization wrapper classes, whereas they are already implemented for v2 of the SDK.

Goal:

Implement client initialization wrapper classes for Java FlowDB to standardize initialization logic and ensure consistency with the v2 architecture.
